The math library includes math related functions that you can use with Numbers.
- In the TouchDevelop editor, click
mathto access the functions described below - In the Block editor, click maths on the left to see the available blocks
The functions available in Touch Develop are:
abs
math -> abs (x : Number) returns Number
returns the absolute value of input parameter x
basic.showNumber(math.abs(-7), 150)
clamp
math -> clamp (min : Number, max : Number, value : Number) returns Number
limits a number to a range (between a min and max number); returns min if value is < min; returns max if value is > max; otherwise, returns value.
basic.showNumber(td.clamp(5, 9, 12), 150)
max
math -> max (x : Number, y : Number) returns Number
returns the larger of two input numbers (x and y)
basic.showNumber(Math.max(9, 7), 150)
min
math -> min (x : Number, y : Number) returns Number
returns the smaller of two input numbers (x and y)
basic.showNumber(Math.min(9, 7), 150)
mod
math -> mod (x : Number, y : Number) returns Number
returns the integer modulus/remainder resulting from the division of the number x by the number y
basic.showNumber(math.mod(9, 7), 150)
pow
math -> pow (base : Number, exp : Number) returns Number
returns the value of the number base raised to the power exp
basic.showNumber(math.pow(3, 3), 150)
random
math -> random (limit : Number) returns Number
returns a random Number between 0 and the parameter limit - 1
basic.showNumber(Math.random(10), 150)
sign
math -> sign (x : Number) returns Number
returns the sign of input parameter x
basic.showNumber(math.sign(-7), 150)
